DESCRIPTION
●The UCC35701/UCC35702 family of pulse width modulators is intended for isolated switching power supplies using primary side control. They can be used for both off-line applications and DC/DC converter designs such as in a distributed power system architecture or as a telecom power source. The devices feature low startup current, allowing for efficient off-line start ing, yet have sufficient output drive to switch power MOSFETs in excess of 500kHz.
●FEATURES
●700kHz Operation
●Integrated Oscillator/ Voltage Feed Forward Compensation
●Accurate Duty Cycle Limit
●Accurate Volt-second Clamp
●Optocoupler Interface
●Fault Counting Shutdown
●Fault Latch off or Automatic Shutdown
●Soft Stop Optimized for Synchronous Rectification
●1A Peak Gate Drive Output
●130A Start-up Current
●750A Operating Current
